Therefore, in this invention, fuel with improved combustion efficiency has the same significance as fuel with reduced greenhouse gas emissions.

Abstract

L'invention concerne un additif pour carburant qui peut être appliqué à n'importe quelle huile combustible organique et permet de fournir une huile combustible présentant un rendement de combustion amélioré, et un procédé de production de celui-ci. Obtenu par fabrication d'un support porte-enzyme par maturation d'une enzyme en permettant une solution enzymatique, préparée par introduction d'une enzyme matière première contenant une lipase dans de l'eau purifiée qui a été modifiée pour sectionner les liaisons hydrogène de l'eau, pour reposer sous agitation intermittente à température normale, ce que provoque le transport de l'enzyme par introduction d'un matériau poreux et permet à l'humidité de sécher naturellement, l'additif pour carburant de la présente invention est capable d'améliorer le rendement de combustion et de supprimer la génération de gaz à effet de serre tout en supprimant la génération de composants nocifs dans le gaz d'échappement sans effets indésirables sur un moteur à combustion, lorsqu'il est utilisé en tant que carburant ou lorsqu'il est ajouté à un carburant.
